tune up an carb 500 miles
Well,
my Jingausu gator 50 qmb136 scooter needed a new carburetor. I have just over 450 miles and had a no idle/stall issue replacing the carb fixed that. I got a new fuel filter & spark plug, a good one (NGK) my scooter had a cheap one houck? So had that replaced. I had all the fluids changed as well. Then took it for a 40-mile ride and what a difference. It idles, runs, accelerates so much better. I had this done 2 weeks ago. I notice 1 issue and that is on a cold start I don't get that fast idle like I used to. BUT it starts 1st try and runs so much better. I don't let it sit more than 4 days or so without running it a few miles. The scooter is garaged & never driven in rain. I wonder if being in Florida may be why I don't get that fast idle? Although the other scooter always had that fast idle when I let it sit a couple of days. It has been quite warm lately. I also checked that the high idle plug is in & tight, I even took it out & reseated it I wonder if it is anything to be concerned about. It sure runs alot better. New carb at 400 miles though? gee. |

When I had my TaoTao, Lancer, the fast idle, enricher, never really worked right.
It would start fast but the drop off within seconds, and stall. I had to baby the throttle until it warmed up a bit to keep it running. I tried a manual choke (enricher) kit; that worked for a while, but then created a vacuum leak. Do you have the old carb.? Perhaps swap the old enricher into the new carb.?. |

If it works better when you're riding it, leave it alone. The GY6 in any size gets better as the miles pile up.
I just bought a 169cc GY6 and I wasn't impressed when I first got it. Even with only 150 miles it's changed a lot. At first it didn't idle worth a damn when cold. Now it runs much better when cold and pulls stronger with each passing mile. You won't believe the difference after a couple of thousand miles. My 2008 150 purred like a kitten after the first thousand and still got stronger after that.
